The San Francisco Giants were expected to be clear sellers at this year’s trade deadline, and they did just that with a slew of trades throughout deadline day.
Their first notable move was shipping Luis Arraez and Caleb Kilian to the Philadelphia Phillies. Later, the Giants traded Heliot Ramos to the New York Yankees, Erik Miller to the Boston Red Sox, and Robbie Ray to the San Diego Padres.
After all four of those big trades, who did the Giants get in return? Ramon Marquez and Henry Lalane are two big names, but they hardly scratch the surface of what’s coming the Giants’ way this summer after their deadline deals.
Get to know all the new prospects the Giants added in fire sale at trade deadline
Luis Arraez and Caleb Kilian to the Phillies for two prospects
The first trade worth diving into is the Arraez deal. In exchange for Arraez and Kilian, the Phillies sent Ramon Marquez and Marty Gair, two right-handed pitchers, to the Giants.
Marquez, according to MLB Pipeline, is the new No. 7-ranked prospect in the Giants’ farm system. He’s a 20-year-old pitcher who is having a breakout season, posting a 1.68 ERA in 59 innings of work with 93 strikeouts. He’s a very fun prospect.
Gair doesn’t rank inside the top-30 prospects, but the 23-year-old right-hander has a 4.50 ERA this season with 66 strikeouts in 36 innings of work as a reliever.
Heliot Ramos to the Yankees for two prospects
Another important trade for the Giants was their deal sending Ramos to the Yankees. Henry Lalane, a left-handed pitcher who is 22 years old, comes in as the Giants’ No. 9-ranked prospect after the deadline.
He has a 2.77 ERA in 78 innings of work this season between Single-A and High-A. Lalane is an intriguing pitching prospect, but not the only one coming back for Ramos.

Kaeden Kent, the son of Hall of Famer Jeff Kent, is a 22-year-old infield prospect coming to San Francisco in the Ramos trade. He’s their new No. 22-ranked prospect.
Kent is a left-handed-hitting shortstop who has a .302 batting average and .792 OPS in 321 at-bats this season at High-A.
Robbie Ray to the Padres for two prospects
While the Ray trade might go under-the-radar due to the return, the package of Joniel Hernandez and Miguel Mendez is noteworthy.
Mendez is the Giants’ No. 14-ranked prospect according to MLB Pipeline, and the 24-year-old right-hander has a 4.79 EA in 35.2 innings of work. There are some questions about Mendez, but he’s still got some intriguing upside.
Hernandez, meanwhile, is just 17 years old, was signed earlier this year, and in 42 games in the Dominican Summer League, is hitting .316 with a .958 OPS with 50 hits, 42 runs scored, 16 doubles, two triples, four home runs, 44 RBIs, 34 walks, 31 strikeouts, and six steals.
Erik Miller to the Red Sox for one player
This trade, sending reliever Erik Miller to the Boston Red Sox, might be the most unexpected. In exchange for Miller, the Giants received former top prospect Marcelo Mayer.

The 23-year-old is currently on the injured list and has struggled during his Major League career. In 114 big-league games, across 332 at-bats, Mayer has 74 hits, 18 doubles, seven home runs, 32 RBIs, 24 walks, 85 strikeouts, a .223 batting average, a .625 OPS, and 0.3 bWAR.
But, there’s still some upside for Mayer, who is under club control through the 2031 season. While it might not be as exciting if the Giants had added him a year ago, Mayer is still a very intriguing pickup for the Giants.
Overall Giants’ haul after the trade deadline.
Buster Posey traded away Luis Arraez, Robbie Ray, Heliot Ramos, and Erik Miller at this year’s deadline.
In return, he got Marcelo Mayer, and their new No. 7 (Ramon Marquez), No. 9 (Henry Lalane), No. 14 (Miguel Mendez), No. 21 (Joniel Hernandez), and No. 22 (Kaeden Kent) ranked prospects alongside Marty Gair.
It’s a massive haul for the Giants, and is a good way for the club to take at least one positive from what was a very disappointing 2026 season up to this point.
